If the performance of the battery does not recover (e.g. the usable time after
each charge has become extremely short), the internal battery may be at the
end of service life. On the home screen, “Apps Sheet” → [Settings] → [About
phone] → [Status] → [Battery status] to check the charging performance of
the internal battery.

◎ Depending on the operation procedure and usage environment, the
temperature inside the product may get high and the product may even
get heated. In such case, charging may stop for security reasons.

lengthen the charging time.

shortens its service life.

charging/incoming indicator may not illuminate soon. However, charging
is in progress.

es in red, force the power off (▶P. 14)
and turn the product on again. If the indicator continues to flash, stop charging
the internal battery and contact an au shop or the Keitai Guarantee Service
Center.
◎ If you stop charging while the charging/incoming indicator still illuminates
during charging, the cell phone may be left not fully charged even if
is displayed on it. In such case, the usage times shorten.
